GridForeignColumn OData Combobox using OData v8

[Mason]

Hi what is the proper way to setup SfCombobox as a EditTemplate using SfDatamanager OData adaptor inside of Foreign column using SfDataManager OData adaptor?

Below is what I have so far but I get an error "Unhandled exception rendering component: Object reference not set to an instance of an object".

<GridForeignColumn AutoFit="true" TValue="KnowledgeBaseArticle" FilterSettings="@(new FilterSettings{Type = Syncfusion.Blazor.Grids.FilterType.Menu })" Field=@nameof(KnowledgeBaseArticle_Category.KnowledgeBaseArticleId) ForeignKeyField="@nameof(KnowledgeBaseArticle.Id)" ForeignKeyValue="@nameof(KnowledgeBaseArticle.Title)" HeaderText="Title" Width="150">

                <SfDataManager Headers=@HeaderData Url="odata/KnowledgeBaseArticles" CrossDomain="true" Adaptor="Adaptors.ODataV4Adaptor">

                </SfDataManager>

            <EditTemplate>

                <SfComboBox ID="KnowledgeBaseArticleId" TItem="KnowledgeBaseArticle" AllowFiltering="true" TValue="int" @bind-Value="@((context as KnowledgeBaseArticle_Category).KnowledgeBaseArticleId)">

                    <ComboBoxFieldSettings Text="Title" Value="Id"></ComboBoxFieldSettings>

                    <SfDataManager Headers=@HeaderData Url="odata/KnowledgeBaseArticles" CrossDomain="true" Adaptor="Adaptors.ODataV4Adaptor">

                    </SfDataManager>

                </SfComboBox>

            </EditTemplate>

        </GridForeignColumn>

Nevermind, I found that I need to explicitly put <ChildContent> around SfDatamanager, is this how you would recommend to do this?

<GridForeignColumn AutoFit="true" TValue="KnowledgeBaseArticle" FilterSettings="@(new FilterSettings{Type = Syncfusion.Blazor.Grids.FilterType.Menu })" Field=@nameof(KnowledgeBaseArticle_Category.KnowledgeBaseArticleId) ForeignKeyField="@nameof(KnowledgeBaseArticle.Id)" ForeignKeyValue="@nameof(KnowledgeBaseArticle.Title)" HeaderText="Title" Width="150">

            <ChildContent>

                <SfDataManager Headers=@HeaderData Url="odata/KnowledgeBaseArticles" CrossDomain="true" Adaptor="Adaptors.ODataV4Adaptor">

                </SfDataManager>

            </ChildContent>

            <EditTemplate>

                <SfComboBox ID="KnowledgeBaseArticleId" TItem="KnowledgeBaseArticle" AllowFiltering="true" TValue="int" @bind-Value="@((context as KnowledgeBaseArticle_Category).KnowledgeBaseArticleId)">

                    <ComboBoxFieldSettings Text="Title" Value="Id"></ComboBoxFieldSettings>

                    <SfDataManager Headers=@HeaderData Url="odata/KnowledgeBaseArticles" CrossDomain="true" Adaptor="Adaptors.ODataV4Adaptor">

                    </SfDataManager>

                </SfComboBox>

            </EditTemplate>

        </GridForeignColumn>
